When we start to see kollel students (that's what they call people who spend all day studying) shooting people, then I'll concede that your comment has merit.
Actually, the study that they engage in is extremely rigorous, and far from idleness.
Nevertheless, there are quite a few religious Israelis who do not work, but spend their time studying instead. I believe that this is a difficult social problem for Israel, and that they should combine their study with work. I don't believe that this sort of sociological group exists in Jewish communities anywhere else in the world. Even in Lakewood, NJ, the center of kollel activity in the US, those who study tend to do so for a few years, not for an entire lifetime.
But that's an issue for another thread, I think.
"I believe that this is a difficult social problem for Israel, and that they should combine their study with work."
I very much support the hesder yeshivot, where the men learn part-time & serve in the army. These people to me are the future of Israel & Israeli defense.
As far as kollel . . . I very much support learning the first few years of marriage. I don't know what percentage in Israel actually commit themselves to longer. Of course, the charedi (ultra-Orthodox) communities emphasize learning over everything else, and these communities exist all over Israel, especially Jerusalem.
Certainly, we Jews need Torah scholars. Some people belong there. And they're hardly idle. (Or violent.) Maybe the problem, as Rodney King may have been trying to say, is that the kollel system is being exploited. There are men who use it to stay out of the army, or to get a meal ticket, or, to find a wife.
Kollel life isn't for everyone. Those who don't belong there, shouldn't be there.
